He's wrong about extinctions. The "natural" rate of extinctions is a barely discernible crackle of background noise in the cascade of human-caused extinctions. And while he's right to lampoon bourgeois "environmentalism," he commits the very same offense that they're guilty of by asserting that we should simply let "nature" take its course.

Plus he's a misanthrope. He should cheer up a bit. Do him good. But then of course he wouldn't be half as funny.
